Q How does the CSV to JSON parser handle quotes and commas?: Our converter implements standard RFC 4180 parser compliance. It properly tracks double-quoted fields, allowing cells to contain internal commas, tabs, semicolons, and even newlines without corrupting the layout.
Q Does this tool attempt to detect variable types?: Yes! By default, the tool will attempt to parse numbers (like "42") and booleans (like "true") into native JSON types rather than plain strings, unless disabled.
